Can anybody tell me how to do it? Anybody have instructions by chance?

Do a search....If I remember there are at least a couple of INJEN intake install threads.

An Injen CAI would be a little different since I have a POP though wouldn't it?

I have a couple of pics on my homepage of that intake on my car. I did not get instructions on mine because I bought it used. I got my instructions from a members site. His name is Greg and he has a website with some good info. I think his screen name is GregP, I'm not sure. If I find anything I will let you know.

I have some pics and the stock Stillen instructions on my web site, for my '99 Maxima.

This might be what you're looking for.

Yup, this is the site I got help from when I need info on installing the intake and before that,the tranny cooler. Thanks Greg for having the writeups and instructions on your website. You saved me a lot of headaches and time.

Yer welcome, and glad I could help. I've been in sort of a lull lately with the car - haven't done much of anything in a while. It's been so cold, the weather de-motivates me.
